Two days of rainforest hiking and wildlife watching between Sirena and San Pedrillo in Corcovado National Park. Expect primary forest, short easy loops at Sirena, a wilder 10–12 km route at San Pedrillo, and an overnight jungle shelter.

Morning light slices through giant figs as a skiff slips away from Drake Bay and the ocean begins to dare you with glints of dolphin and sea turtle. An hour and change later you step onto Sirena’s broad sand and follow short, flat trails into a young forest—47 years into regrowth—where coatis and agoutis move with casual curiosity and birds treat the canopy like a highway.

Morning light slices through giant figs as a skiff slips away from Drake Bay and the ocean begins to dare you with glints of dolphin and sea turtle. An hour and change later you step onto Sirena’s broad sand and follow short, flat trails into a young forest—47 years into regrowth—where coatis and agoutis move with casual curiosity and birds treat the canopy like a highway.
On day two the jungle tightens. San Pedrillo drops you into primary rainforest: trees that have been standing far longer than any map, roots like living ropes and a silence that feels like a held breath. This is Corcovado — one of the world’s most intact lowland rainforests, protected since the 1970s — where predator and prey keep the deepest rhythms. Geologically the Osa Peninsula is a rugged wedge of volcanic and sedimentary rock, its soils feeding the dense biodiversity that draws researchers and curious travelers alike.
Expect 10–12 km of walking in wild, often muddy terrain on the San Pedrillo leg, with shorter, easier loops at Sirena. Trails range from well-defined boardwalks to narrow, irregular jungle paths; humidity and leeches are possible. Pack light, keep hydrated, and move quietly: the payoff is close encounters or the sudden chorus of howler monkeys and scarlet macaws overhead. Nights are spent in a simple jungle shelter between San Pedrillo and Los Planes; bring a headlamp and dry bags. Guides manage logistics, park permits, and wildlife etiquette—this is an immersive, pragmatic rainforest experience built for walkers who want both wildlife and real backcountry.
The San Pedrillo leg is moderate: expect uneven, sometimes muddy trails and a faster pace to maximize wildlife opportunities—good stamina and steady footing are helpful.
Guides typically handle park permits and logistics; confirm with the operator whether entrance fees are included in the booking.
Common sightings include capuchin and howler monkeys, coatis, agoutis, scarlet macaws, and, with luck, tayras or big cats—predators are elusive and sightings can’t be guaranteed.
Shelter is basic and functional—expect a roofed communal space and simple sleeping arrangements; bring a dry bag and lightweight sleeping liner for comfort.
Top Trails Corcovado operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
